“Previous research shows that thoughts of death lead individuals to strongly defend world views that maintain their self-esteem,” Laroche says.

“In other words, thinking about death will likely make people cling even more strongly to their beliefs because it’s a way to cope with mortality.”

Laroche and Nepomuceno wanted to test this assumption with anti-consumers — people who voluntarily resist consumption out of a sense of frugality or desire to live simply, and with over-consumers — folks who shop till they drop, no matter the season.

The researchers ran two experiments with 503 North American university students. The respondents were first asked to answer questionnaires identifying their tendency to resist consumption. They were then randomly assigned to one of two groups:

In the “death thoughts” group, participants were asked to describe what they would feel if they were dying.

In the control group, participants were asked to report what they would feel if they were submitted to a painful dental procedure.

Anti-consumers seem to care less about consumption than over-consumers!

Afterwards, participants indicated their inclination to purchase a series of products. By comparing the participants in each condition, the researchers were able to identify individual tendencies to increase or reduce consumption due to thoughts of death.

“Our expectation was that the anti-consumption individuals would become even more inclined to resist consumption. This would indicate that for them, resistance was an important source of self-esteem,” Nepomuceno says.

“In fact, we found that anti-consumers were not influenced by thoughts of death, which suggests that they do not believe that resistance to consumption is a source of self-esteem. In other words, anti-consumers seem to care less about consumption than over-consumers!”

Interestingly, among consumers inclined to over-consume, the researchers found that thinking about death made them even more likely to buy.

“This indicates that such consumers see purchasing and having goods and services as an important source of self-esteem. When they think about death, they become more inclined to buy because this helps them feel better about themselves,” Nepomuceno explains.

He and Laroche, who was recently named editor-in-chief of the Canadian Journal of Administrative Sciences, hope that the results of this study will arm the general public — especially those inclined toward retail therapy — with a better understanding of how consumption is influenced by situational factors. They also aim to show the occurrence of such influences without the full knowledge of the consumer.

“A person who knows that thoughts of death can lead to over-consumption is now in a position to avoid exposing themselves to such thoughts before shopping,” concludes Laroche.
